Spreenkler Talent Labs is running its second hackathon at 11 a.m. Saturday, uniting software developers and designers into teams tasked with creating "useful and cool software" in just 24 hours.

The first hackathon lured creative talent from all over, fielding 11 teams with about 40 developers. Saturday's free event will be hosted among multiple cities — Milwaukee, Chicago, Madison and New York — and the Milwaukee venue is at the University of Wisconsin-Milwaukee's Peck School of the Arts Kenilworth Building, 1915 E. Kenilworth Place, on the third floor.

The apps are judged on their completion, creativity and scalability, with about $25,000 in prizes awarded accordingly. The first-place team has the chance to enter Spreenkler’s Seed Incubator and build a company based on its 24-hour effort. In addition to my story on the first hackathon, Spreenkler offers several videos about the Talent Labs, the event and the players involved. As you can tell from the video I've included below, they're working hard and having a good time.
